INTRODUCTION
Congratulations
on
your
purchase
of
the
CEL-24X
Digital
Sound
Level
Meter.
The
CEL-24X has
been
designed
to
perform
accurate
noise
measurements
through
a
wide
decibel range.
The
CEL-24X
is
a
digital
sound
level
meter,
designed
for
stable,
reliable
performance,
fully
compliant
with
international
sound
level

standards.
The dB24 software package was developed to enable the CEL-24X to interface with
any PC conforming to the
minimum PC requirements. dB24 software allows the ‘C’
and ‘A’ weighted sound pressure to be stored to your PC every second, with the time
weighting (Fast, Slow or Impulse) currently selected on the CEL-24X.
This
Operator’s

DOWNLOADING DATA FROM CEL-242/246 INSTRUMENTS
CEL-242 and CEL-246 instruments have on-board memory which can be
downloaded to a PC. During the installation of dB24, a utility called ‘Casella Drive’ is
installed at the same time which continually runs in the system tray. The icon
will
be displayed in the system tray. ‘Casella Drive’ allows CEL-242 and CEL-246
instruments to be viewed as a removable drive in a similar way to a USB flash
memory drive. Ensure the dB24 software component described above is closed as
this will prevent CEL-242/246 instruments connecting to ‘Casella Drive’.
Handbook No. HB3336-03

1. Connect the USB lead as detailed in this manual to a CEL-242 or CEL-246
instrument.
2. The instrument will be automatically detected and downloaded. The window
shown in Figure 4 will be displayed in the bottom right of the screen and the
instrument will begin to download.
Figure 4: Downloading
3. Once the download has completed, an explorer window will automatically appear
which will show the stored data files as individual .csv files which can be open on
spreadsheet packages as required, as shown in Figure 5. Files should be saved
to the computer hard drive prior to editing. The CEL-242/246 will not store edited
files.
4. Settings to the ‘Casella Drive’ utility can be made by right clicking on the icon in
the system tray to give 2 options:
a. ‘Open Explorer window after download’. This option will cause the
application to open the new drive in a separate Explorer window once
the instrument has been successfully downloaded.
b. ‘Minimise main window on startup’. This causes the application to
automatically minimise to the ‘system tray’ area of the ‘taskbar’ once
loaded.
Figure 5: An Explorer Window Following Successful Download
.
Notes: If for some reason ‘Casella Drive’ is not shown in the system tray then
it needs to be started manually. On your PC, press the ‘Start’ button in the
bottom left of the screen, then select
All Program | Casella CEL | Casella Drive.
